UNIT 5Internet互联网The Internet is a giant network of computers located all over the world that communicate with each other. Internet是由位于世界各地相互通信的计算机连接而成的巨大的计算机网络。

The Internet is a international collection of computer networks that all understand a standard system of addresses and commands, connected together through backbone systems.Internet在一起。

It was started in 1969, when the U.S. Department of Defense established a nationwide network to connect a handful of universities and contractors.Internet始建于1969The original idea was to increase computing capacity that could be shared by users in many locations and to find out what it would take for computer networks to survive a nuclear war or other disaster by providing multiple path between users.哪一种计算机网络能够在核战或其他灾难中幸存。

People on the ARPNET (as this nationwide network was originally called)quickly discovered that the could exchange messages and conduct electronic “conferences”with distant colleagues for purposes that had nothing to duo with the military industrial complex.ARP-NET(这种全国网络最初的名称)If somebody else had something interesting stored on his or her computer, it was a simple matter to obtain a copy. (assuming the owner did not protect it)如果另外一些人在其计算机中存有有趣的东西,得到其拷贝是很容易的事(假定拥有者没有进行保护). Over the years, additional networks joined which added access to more and more computers.几年间,新的网络接入使越来越多的计算机加入近来。

Unit 5 多址技术Unit 5-1第一部分：多址技术：频分多址、时分多址、码分多址多址方案用于使许多用户同时使用同一个固定带宽的无线电频谱。

在任何无线电系统中分配的带宽总是有限的。

移动电话系统的典型总带宽是50MHz ，它被分成两半用以提供系统的前向和反向连接。

任何无线网络为了提高用户容量都需要共享频谱。

频分多址（FDMA ）、时分多址（TDMA ）、码分多址（CDMA ）是无线系统中由众多用户共享可用带宽的三种主要方法。

这些方法又有许多扩展和混合技术，例如正交频分复用（OFDM ），以及混合时分和频分多址系统。

不过要了解任何扩展技术首先要求对三种主要方法的理解。

频分多址在FDMA 中，可用带宽被分为许多个较窄的频带。

每一用户被分配一个独特的频带用于发送和接收。

在一次通话中其他用户不能使用同一频带。

每个用户分配到一个由基站到移动电话的前向信道以及一个返回基站的反向信道，每个信道都是一个单向连接。

在每个信道中传输信号是连续的，以便进行模拟通信。

FDMA 信道的带宽一般较小（30kHz ），每个信道只支持一个用户。

FDMA 作为大多数多信道系统的一部分用于初步分割分配到的宽频带。

将可用带宽分配给几个信道的情况见图5.1和图5.2。

时分多址TDMA 将可用频谱分成多个时隙，通过分配给每一个用户一个时隙以便在其中发送或接收。

图5.3显示如何以一种循环复用的方式把时隙分配给用户，每个用户每帧分得一个时隙。

TDMA 以缓冲和爆发方式发送数据。

因此每个信道的发射是不连续的。

待发送的输入数据在前一帧期间被缓存，在分配给该信道的时隙中以较高速率爆发式发送出去。

TDMA 不能直接传送模拟信号因为它需要使用缓冲，因而只能用于传输数字形式的数据。

由于通常发送速率很高，TDMA 会受到多径效应的影响。

这导致多径信号引起码间干扰。

TDMA 一般与FDMA 结合使用，将可用的全部带宽划分为若干信道。

这是为了减少每个信道上的用户数以便使用较低的数据速率。

电子通讯的普及英语作文英文：The popularity of electronic communication has changed the way we interact with others. With the advent of smartphones, social media, and email, it has become easier than ever to stay connected with friends, family, and colleagues. Personally, I find that electronic communication has greatly improved my ability to keep in touch with people, especially those who live far away from me.For example, I have a friend who lives in another country, and without electronic communication, it would be nearly impossible for us to stay connected. However, thanks to messaging apps and video calls, we are able to chat regularly and share updates about our lives. This has strengthened our friendship and made the distance between us feel much smaller.In addition, electronic communication has also made it easier for me to collaborate with colleagues on work projects. Instead of having to schedule in-person meetings, we can simply send emails or use project management toolsto communicate and share ideas. This has not only saved us time, but has also allowed us to be more efficient in our work.中文：电子通讯的普及改变了我们与他人互动的方式。
